139-7850: Charging Alternator

Description: Cat® alternators are designed to energize the battery to power your machine, regardless of operating conditions. They are proven top-notch tough, durable and reliable, even at low idle. There are two categories: Brush-Type Design uses one-piece brushes for less maintenance, and constant-pressure springs for even brush wear; and our Brushless Design, with fewer moving parts, tighter air gap tolerances and superior sealing for longer life in harsh environments (dirt, dust, heat or cold). Cat® Alternators are quiet, compact, and lightweight, designed to be part of a balanced electrical system, and each unit is rigorously tested, so you know you’re getting genuine Cat® reliability. Off-the-shelf availability minimizes your down time.
